SPECIFICATION arming part of Letters Be it known thatoI, OTTO W;SIEBENHAAR i a citizen of the United States, residing at La-,

doga, in the county of Fond du Lac and State{ of Wisconsin, haveinvented certain new and useful Improvements in Horseshoes; and I do:

hereby declare the following to be a full,elear,

" and exact descriptionwof theinvention, such as 1 will enable othersskilled inthe art to which it appertains to makeand use the same.

This invention has relation to the type of horseshoes having a yieldingtread portion to relieve jar and prevent the attendant ailmentsto horseswhen driven over hardand stony roads. v

For a full description of the invention and the merits thereof, and alsoto acquire a knowledge of the details of construction of the means foreffecting the result, reference isto be had to the appended descriptionand drawings hereto attached.

While the essential and characteristic features of the invention are notnecessarily susceptible of modification, still the preferred embodimentof the invention is illustrated in the accompanying drawings, in which-Figure 1 is a plan view of the horseshoe as seen from the tread-surface.Fig. 2 is a side elevation. Fig. 3 is a perspective View of the footmeniber. Fig. 4 is a perspective view of the tread member.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the same vreference characters.

The horseshoe comprises the foot member 1 and tread member 2, the formerbeing COD", structed either of wrought-iron or common steel and thelatter of steel capable of being tempered so as to resist wear andretain resiliency, whichv is essential to "the effectiveness of thearticle when in service.

The tread member 2 is comparatively thin and light, and its toe and'heel portions are deflected away from the plane of the foot member 1 toprovide spring portions 3 and 4. The intermediate portion of thetread'mem:

her is thick and provided with openingsfi to receive the fastenings 6,by means of which the membersland 2 are secured together,

said fastenings being machine-screws and t .1 ...V.Y, Batent No. 657,298,dated September 4, 1900. f Application filed June 25, 1900 serialllo. 21,542 (1T0 model.) i l parts of the foot member 1. blocks inaddition to excluding foreign mathaving their heads countersunk in thelower v face of the member 2. This construction admits ofthe treadmember. being readilyyreplaced when'wornor removed from the foot memberfor any purpose when desired. In order to add to the life of the treadmember and prevent slipping, it isprovided at its toe and heel with theusual calks, which by preference form an integralpartof the said member.By having the toe and heel portions oppositely inclined or deflected thehorseshoe as a whole is rendered yielding, so as to compensate for jarand prevent the usual ailmen ts resulting from driving a horse over hardand stony roads when shod with the common shoe. 1 l i In order toprevent gravel, dirt, and other foreign matter lodging in the angularspaces formed between the foot and tread members,

rubber blocks 7 and 8 are interposed between the spring portions 3 and 1and the adjacent These rubber ter from gaining access between themembers of the horseshoe supplement thespr'ing action of the parts 3 andland prevent any metallic ring incident to the steel tread member 2striking a stone or like object.

The foot member 1 is comparatively thin and is reinforced at its innerand outer edges by flanges 9, which also serve. to retain the rubberblocks 7 and 8 against casual displacement. Nail-holes 10 are formed inthe foot member 1 adjacent to the outer flange and admit of the passageof the nails by means of 'nailswhen the horseshoe is in position. "In-Tner and outer clips 12 are located at the toe of the tread member 2 andcooperate with the flanges 9 at the toe portion of the member 1 andprevent either outward or inward displacement of the elastic block '7.The heel portions of the tread member are flanged to provide seats 13,which act in conjunction with the adjacent flanged portions of the footmember i0 mm sary to trimfthehoof.
